In "production" skins, what I like to do is instead of using a "dummy" option to force a one-time dynamic reading of options, is to use the DynamicVariables option itself.[!SetOption SomeSection DynamicVariables "0"]

This way you can still understand "why" you placed that there at a later time when the skin isn't so fresh in your mind. Or if you happen to distribute the skin, other users can attempt to understand what you are doing. [!SetOption Something Dummy ""] isn't going to make a lot of sense to most users, and might even throw you for a loop 2 years later when updating your skin.
